The Wombat wing is made from foam for super durability. The Wombat is recommended for pilots of all skill levels including the "never flown before beginner." The Wombat airfoil is computer designed and tested to ensure superior flight performance. Stability for turns and inverted performance are designed into the airfoil. This is the cheapest form of Rc Airplanes for combat and those who want to start flying airplanes.The Wombat Basic Kit is meant for customers who already have radio gear from other airplanes or are replacing an old beat up wing with a new one. We recommend standard size servos and receiver to ensure proper balancing.
